4 Claims. 20-49) This application is a substitute of the abandoned application entitled Window, which was filed on November 18, 1927, and bore Serial #234,246.

The present invention is concerned with improvements in windows of the type in which upper and lower sliding sashes are arranged to be swung inwardly for purposes of cleaning.

An object of the invention is to provide a window of this character in. which the sashweights and associated mechanism are completely eliminated, and the consequent over-all size of the window frame materially reduced.

Another object of the invention is to provide a window of this character of extremely simple, practical construction, which will be rugged, durable and efficient in use, and well suited to the requirements of economical manufacture and convenient manipulation.

With the above noted and other objects in view, the invention consists of certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein Figure 1 is a perspective view of a window embodying the present invention, showing the lower sash swung partially inward and the upper sash partially lowered.

Figure 2 is an enlarged fragmentary view of one of the lower sashes.

Figure 3 is a perspective view of one of the slide members which mount the lower sash.

Figure 4 is a vertical sectional view through the window taken approximately on the line 44 of Figure 1, and indicating in dotted lines an inwardly swung position of the upper sash.

Figure 5 is an enlarged sectional detail on the line 55 of Figure 1.

Figure 6 is a sectional plan view on the line 6-6 of Figure 4.

Figures '7, 8 and 9 are perspective views of the three members of the spring housing.

As suggested in the preamble, the window frame of the present invention is entirely devoid of the usual boxes which house the sashweights and includes side members 10, a sill II, and a top l2. At each side of the window, inner and outer molding strips I3 and I4 and a central parting strip l5 extend from top to bottom of the frame, these strips are grooved in order to define locking guideways for slide plates is and H, which slide plates carry the upper and lower sashes l8 and !9 respectively, and are of the same length as the sashes which they carry. Each slide plate is provided with tongues 20 working in the grooves of the parting and molding strips, and is provided at its rear edge with an inwardly projecting flange 2| cooperating with a groove 22 in the associated sash to prevent the latter from swinging outwardly.

The upper and lower sashes are pivotally connected at their lower corners to the respective slide plates which carry them, this pivotal connection being a unique one, and serving a double function as will be later described. Registering cylindrical sockets 24 and 25 are provided in the sashes and slides respectively. Circular caps 26 and 21 are inserted in the pockets 24 and 25, and anchored. by driving them home in the pockets due to the presence of spurs 2B struck from the caps. These caps loosely receive the ends of a tubular spring housing 29, which housing conceals and protects a coiled spring 30 anchored at its respective ends to the anchored caps 26 and 21. This spring is of the expansion type, and backed against the sashes exerts a strong spring pressure against the slide plates holding them snugly against the sides of the window frame so that the sashes are automatically secured at any elevation to which they may be moved, and sash cords and weights are eliminated.

The springs 30, due to the fact that their ends are anchored, also exert a torsional action to resist inward swinging movement of the sashes about tubes 29 as pivots. Thus, the springs materially assist return of the sashes from the inwardly swung position illustrated in Figure 4 to their normal vertical position.

In order to prevent any accidental movement of the sashes, each sash is provided with one or more bolt mechanisms 35 of conventional construction coacting with keepers 36 in the slide plates.

From the foregoing description, it will be apparent that the two sashes may he slid up and down in the frame in the usual manner, and may be selectivelyswung inwardlyfor cleaning purposes by the simple expedient of retracting the bolts and using the bolt handles to pull the sashes forwardly against the action of their springs. In order that the upper sash may clear the rail 2| of the lower sash slide, the upper sash slides preferably project inwardly somewhat beyond the molding strip asindicated in Figure 6.

Obviously, various changes and alterations might be made in the general form and arrangement in the channels of the frame, a sash ar- 7 H ranged between the slide plates, means pivotally connecting the sash to the slide plates and also causing the sash to move with said plates, said means comprising tubes whose ends are pocketed in registering sockets in the sash and plates,

frame, a sash arranged between the slide plates,

means pivotally connecting the sash to the slide said sockets having liner caps therein providing bearings for the tubes and anchored to the sash the slide plates into tight engagement with the frame, and also resisting opening pivotal movement of the sash.

2. A window construction including channeled frame, slide plates guided for vertical movement in the channels of the frame, a sash arranged between the slide plates, means pivotally connecting the sash to the slide plates and also causing the sash to move with said plates, said means comprising tubes whose ends are pocketed in registering sockets in the sash and plates, said sockets having liner caps therein providing bearings for the tubes and anchored to the sash and plates, and springs of the coiled expansion type housed in the tubes and bearing on the caps, thereby urging the plates into tight engagement with the frame.

3. A window construction including a frame, slide plates guided for vertical movement in the plates and also causing the sash to move with said plates, said means comprising tubes whose ends are pocketed in registering sockets in the sash and plates, said sockets having liner caps therein providing bearings for the tubes and anchored to the sash and plates, and springs of the coiled expansion type housed in the tubes and anchored to the caps, whereby the springs resist the opening movement of the sash on its pivots.

4. A window construction including a channeled frame, slide plates guided for vertical movement in the channels of the frame, a sash arranged between the slide plates, and unitary structures pivotally mounting the sash on the slide plates and also causing the sash to move with said plates, each of said unitary structures comprising a tube whose ends are disposed in sockets in the sash and one of the slide plates, caps in the sockets anchored to the sash and said plate and loosely surrounding the ends of the tube, and a spring within the tube and engaging the caps urging the plate into tight engagement with the sash.
